T The development of cultural facilities in sleman regency has become an important agenda in response to the increasing number of artistic activities, the need to preserve local traditions, and the demand for public spaces that facilitate social interaction within the community. through the terms of reference (kak), the sleman regency government has planned the development of a cultural park as an integrated facility for performances, exhibitions, education, and creative activities. this design requires an approach that focuses not only on functional and aesthetic aspects but also considers environmental sustainability and the local identity of sleman, which is strongly characterized by agrarian traditions, arts, and local wisdom.this final project proposes the design of the sleman cultural park using an eco-cultural architecture approach, which integrates ecological architectural principles with local cultural values to create spaces that are sustainable, contextual, and meaningful to the community. the approach is implemented through a combination of ecological strategies—including energy conservation, water management, green spaces, microclimate control, and the use of local materials—with cultural expressions of sleman, including traditional javanese architecture, village settlement patterns, agrarian landscapes, and regional motifs applied to architectural elements.the design method involves the collection of primary and secondary data, programmatic analysis using the hectteas theory, and the formulation of design concepts based on the design framework of kathryn h. anthony. the cultural park\'s spatial program—including a joglo pendopo, multipurpose performance hall, amphitheatre, exhibition spaces, educational facilities, art workshops, outdoor public spaces, and landscape conservation areas—is designed to represent the integration of ecological and cultural aspects within an interconnected and cohesive development.this design research is expected to produce a design concept for the sleman cultural park that not only meets the functional and technical requirements of public buildings but also provides an ecological and inclusive cultural space that responds to the natural and cultural characteristics of sleman. thus, the project is expected to serve as an example of a harmonious, adaptive, and sustainable application of eco-cultural architecture in the special region of yogyakarta.
